BRAKE-ROD HANDLE.-

SPECIFICATION forming part of Letters Patent No. 351,735, dated November2, 1886.

Application filed September 17, 1886. Serial No. 213,804. (No model.) I

To all whom it may concern:

Beit known that I, J oHN A. BRILL, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inBrake-Rod Handles, of which the following is a specification, referencebeing had therein to the accompanying drawings, whereinrod and of thehandle or wheel therefor embodying my improvements. Fig. 2 is a verticalsection, partly in elevation, showing engagement of clutch-wheelswhen'the handle is turned to rotate the brake-rod. Fig.3 is a like viewshowing position of loose clutchwheel when handle is reversely turnedorrotated without turning the brake-rod; andFig. 4 is a section on line1 1, Fig. 2.

My invention has relation to street-car brakerod handles or wheels ofthe form wherein the handle when turned in one direction rotates thebrake-rod, and when turned in an opposite direction moves independent ofor without turning the brake-rod; audit has for its object to provideasimple, economical, and durable form of clutch-wheel mechanism betweenor connecting the handle and brake-rod.

My invention accordingly consists of the o combination, construction,and arrangement of parts, as hereinafter described and claimed,

having reference particularly to a brake-rod having fixed to it near itsupper end a clutchwheel', to which the handle is swiveled the up- I perend of the brake-rod being journaled, or

has a bearing in'the handle, and has loosely mounted on it, so as toslide up and down, a clutch-wheel having a spring-pressure for causingit to normally engage with the clutch- 0 wheel fixed to the brake-rod,and having also side lugs which fit into vertical recesses in thehandle, to engage the loose clutch-wheel with the handle and cause themto turn together as the handle is rotated in either direction.

4 In the drawings, A represents a brake-rod for street or other cars,having a reduced upper end, a. Below the latter is firmly secured to rodA, in any suitable manner, a clutchwheel, B, and beneath the wheel B isa collar or platform, 0. The wheel B and collar 0 may be separate andcorrespondingly secured Figure l is an elevation of part of the brake torod A, or they may be integral. The'handle D is provided with a lower orbottom socket or hollow hub, d, the edged of which rests upon the collar0. The handle-socket d is formed with inside oppositely-located verticalrecesses or slots, d, and with preferably outside lugs or fillet-pieces,d through which pass pins or screws d, one on each side of the socket d.These pins engage with an annular peripheral groove, b, formed onclutch-wheel B, to swivel the handle or" its socket d to said wheel. Twopins, d", are provided for swiveling the handle to the clutch-wheel B,to make a strong connection between said parts, and to avoid lateralstrain between the handleand its swivel connection when the brakes areapplied.

Above the fixed clutch-wheel B, and loosely mounted upon the reduced enda of rod A is a second clutch-wheel, E, the teeth 6 orwhich normallyengage with the teeth I) of wheel B. This normal engagement ismaintained by the pressure or action of a spiral spring, F, surroundingend a, and having one of its ends abutting against wheel E, and the 7 5other against a shoulder, g, of a socket or re cess, G, in the handle D,above socket d. The upper extremity of the end a of rod A has a bearing,h, in the handleD, to give firmness or support to the handle.

The loose clutch-wheel E has oppositely-located side or peripherallugs,e,which enter the slots or recesses d in socket d to engage saidwheel with socket (I, so that the handle D cannot turn in any directionwithout rotating the loose clutch-wheel E.

The operation is as follows: When the handle is turned from right toleft, the loose clutchwheel E engages with the clutch-wheel B, fixed torod A, and the latter is rotated to apply the brakes. When thehandleisreversely rotated, the wheel E moving therewith, and being loose onshaft or end a, its teeth ride up on those of wheel B and raise thewheel E out of engagement with wheel B, as shown in Fig. 3, to 5 admitof turning the handle in said last-named direction without rotating thebrake-rod.

The bearing h of the end a of rod A in handle D may be of any desiredlength conformable to the shape of the handle, and any suit- 10o ableform of teeth for the clutch-wheel may be employed.

lVhat I claim is-- 1. A brake-rod having near its upper end a collar, afixed ratchet-wheel of a diameter less than that of the collar, a looseratchet-wheel of a diameter corresponding with that of the fixedratchet, a downwardly-acting spring for the loose ratchet-wheel, and ahandle or wheel having a socket inelosing said ratchet-wheels andspring, a shoulder for the upper end of the spring to abut or actagainst, and a swiveled connection with said collar, substantially asset iorth.

2. A brake-rod having a clutch-wheel, B, and collar 0, a handle havingsocket d resting upon collar 0 and swiveled to wheel B, and aclutch-wheel, E, loose on the brake-rod and turning with the handle,substantially as set forth.

3. The combination of brake-rod A, having elutchavheel B, provided withgroove b,ch1tcl1- wheel E, loose on said rod and having springpressuredevices, handle D, having socket d, swiveled to wheel B by means of pins(1* entering clutch-wheel groove b, and devices for loosely connectingwheel E with handle D, substantially as set forth.

4. The handle D,having bearing h, recess (1, and socket d, provided withvertical recesses cl, in combination with rod A, having clutchwheel B,swiveled to socket d, loose clutchwheel E, having lugs e, fittingrecesses d, and spring F, substantially as set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

JOHN A BRILL.
